Martians are a sapient humanoid race from the planet Mars. Their external appearance is indistinguishable from Humans, save for a pair of retractable antennae. It appears that young Martians lose their "baby antennae" at some point, after which they are replaced by "adult antennae". Martians also possess a number of outstanding psychic abilities. They can communicate telepathically with other life forms (including non-sapient ones), and may influence minds as well as read them. They can also levitate objects, turn themselves invisible and exert temporal control over people, either freezing them or speeding them up.
